android 开源项目

   最近在对开发项目的性能进行优化。由于项目里涉及了大量的缓存处理和数据库运用,需要对数据库进行频繁的读写、查询等操作。因此首先想到了对整个项目的数据库框架进行优化。

   原先使用android本身内置的sqllite,也就是用的最基本的SQLiteOpenHelper方法,这种方法对自己来说比较方便易懂。但是在使用过程中感觉很繁琐,从建表到对表的增删改查等操作,如果表对象的属性很多,就需要使用大量的代码来执行建表、插入等。在代码执行中还需要对数据库和游标的进行及时关闭(开启使用,用完关闭),而且还需要部分sql语言,这在开发中产生bug进行调试时尤其不方便。

     目前android经常用的orm框架主要有greenDAO、OrmLite、AndrORM。 综合了网上的各种评价,greenDAO的运行效率最高,内存消耗最少,性能最佳。因此决定采用greenDAO框架,对项目的orm框架进行改进。

greenDAO与ORMLite性能对比


经过两天的修改,终于将项目里的数据库相关的都优化完了。在这过程中,发现greenDAO的性能确实不错,而且使用相当方便,不再需要涉及到任何的sql语言,可以直接通过对象类进行建表、增删改查等,尤其是api接口又方便易懂。在摸索学习中发现国内相关学习资料实在实在是太少,遂决定在此记录下自己对使用这个orm框架的一些心得和方法总结。


一、greenDAO相关

1.greenDAO官网:http://greendao-orm.com/

2.项目下载地址:https://github.com/greenrobot/greenDAO(或者官网)

greenDAO是一个可以帮助Android开发者快速将Java对象映射到SQLite数据库的表单中的ORM解决方案,通过使用一个简单的面向对象API,开发者可以对Java对象进行存储、更新、删除和查询。

greenDAO的主要设计目标:

   *最大性能(最快的Android ORM)

   *易于使用API

   *高度优化

   *最小内存消耗


二、使用步骤

官方Demo里共有六个工程目录,分别为:

(1).DaoCore:库目录,即jar文件greendao-1.3.0-beta-1.jar的代码;

(2).DaoExample:android范例工程;

(3).DaoExampleGenerator:DaoExample工程的DAO类构造器,java工程;

(4).DaoGenerator:DAO类构造器,java工程;

(5).DaoTest、PerformanceTestOrmLite:其他测试相关的工程

(一)DAO类构造

首先需要新建一个java工程来生成DAO类文件,该工程需要导入greendao-generator.jar和freemarker.jar文件到项目中。

在main方法中,

1
Schema schema =  new  Schema( 3 "de.greenrobot.daoexample" );

该方法第一个参数用来更新数据库版本号,第二个参数为要生成的DAO类所在包路径。


然后进行建表和设置要生成DAO文件的目标工程的项目路径。

1
2
3
addNote(schema);
addCustomerOrder(schema);
new  DaoGenerator().generateAll(schema,  "../DaoExample/src-gen" );

其中src-gen这个目录名需要在运行前手动创建,否则会报错。


如果运行后出现以下错误,则导入DaoGenerator项目的dao.ftl文件即可(或者直接使用DaoGenerator来生成DAO文件)。

运行后出现以下的提示说明DAO文件自动生成成功了,刷新一下DaoExample项目即可看到。

Processed  3  entities in 204ms


运行后可以看到,DaoExample项目src-gen下面自动生成了8个文件,3个实体对象,3个dao,1个DaoMaster,1个DaoSession.


(二)创建表

1.创建一个实体类

1
Entity note = schema.addEntity( "Note" );

默认表名就是类名,也可以自定义表名

1
dao.setTableName( "NoteList" );

greenDAO会自动根据实体类属性创建表字段,并赋予默认值。例如在数据库方面的表名和列名都来源于实体类名和属性名。默认的数据库名称是大写使用下划线分隔单词,而不是在Java中使用的驼峰式大小写风格。例如,一个名为“CREATIONDATE”属性将成为一个数据库列“CREATION_DATE”。


设置一个自增长ID列为主键:

1
dao.addIdProperty().primaryKey().autoincrement();


设置其他各种类型的属性:

1
2
3
dao.addIntProperty( "cityId" );
dao.addStringProperty( "infoType" ).notNull(); //非null字段
dao.addDoubleProperty( "Id" );

在生成的实体类中,int类型为自动转为long类型。

如果在编译过程中出现以下错误,那么有可能是主键的类型错误所致:

1
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String


      在使用greenDAO时,一个实体类只能对应一个表,目前没法做到一个表对应多个实体类,或者多个表共用一种对象类型。后续的升级也不会针对这一点进行扩展。


(二)表的增删改查

     增删改查相当方便,完全的面向对象,不需要涉及到任何的sql语言。

1.查询

范例1:查询某个表是否包含某个id:

1
2
3
4
5
6
7
public  boolean  isSaved( int  ID)
{
     QueryBuilder qb = saveListDao.queryBuilder();
     qb.where(Properties.Id.eq(ID));
     qb.buildCount().count();
     return  qb.buildCount().count() >  0  true  false ;
}


范例2:获取整个表的数据集合,一句代码就搞定!

1
2
3
4
public  List getPhotoGallery()
{
     return  photoGalleryDao.loadAll(); // 获取图片相册
}


范例3:通过一个字段值查找对应的另一个字段值(为简便直接使用下面方法,也许有更简单的方法,尚未尝试)

1
2
3
4
5
6
7
8
9
10
11
12
13
14
/** 通过图片id查找其目录id */
public  int  getTypeId( int  picId)
{
     QueryBuilder qb = photoGalleryDao.queryBuilder();
     qb.where(Properties.Id.eq(picId));
     if  (qb.list().size() >  0 )
     {
         return  qb.list().get( 0 ).getTypeId();
     }
     else
     {
         return  - 1 ;
     }
}


范例4:查找所有第一姓名是“Joe”并且以lastname排序。

1
2
3
4
List joes = userDao.queryBuilder()
.where(Properties.FirstName.eq( "Joe" ))
.orderAsc(Properties.LastName)
.list();


范例5:多重条件查询

(1)获取id为cityId并且infotype为HBContant.CITYINFO_SL的数据集合:

1
2
3
4
5
6
7
public  List getSupportingList( int  cityId)
{
     QueryBuilder qb = cityInfoDao.queryBuilder();
     qb.where(qb.and(Properties.CityId.eq(cityId),Properties.InfoType.eq(HBContant.CITYINFO_SL)));
     qb.orderAsc(Properties.Id); // 排序依据
     return  qb.list();
}


(2)获取firstname为“Joe”并且出生于1970年10月以后的所有user集合:

1
2
3
4
5
QueryBuilder qb = userDao.queryBuilder();
qb.where(Properties.FirstName.eq( "Joe" ),
qb.or(Properties.YearOfBirth.gt( 1970 ),
qb.and(Properties.YearOfBirth.eq( 1970 ), Properties.MonthOfBirth.ge( 10 ))));
List youngJoes = qb.list();


范例6:获取某列对象

1
picJsonDao.loadByRowId(picId);



2.增添/插入、修改

插入数据更加简单,也是只要一句代码便能搞定!

1
2
3
4
public  void  addToPhotoTable(Photo p)
{
     photoDao.insert(p);
}


插入时需要new一个新的对象,范例如下:

1
2
3
4
5
6
7
DevOpenHelper helper =  new  DaoMaster.DevOpenHelper( this "notes-db" null );
  db = helper.getWritableDatabase();
  daoMaster =  new  DaoMaster(db);
  daoSession = daoMaster.newSession();
  noteDao = daoSession.getNoteDao();
  Note note =  new  Note( null , noteText, comment,  new  Date());
  noteDao.insert(note);


修改更新:

1
2
photoDao.insertOrReplace(photo);
photoDao.insertInTx(photo);


3.删除:

(1)清空表格数据

1
2
3
4
5
/** 清空相册图片列表的数据 */
public  void  clearPhoto()
{
     photoDao.deleteAll();
}


(2)删除某个对象

1
2
3
4
5
6
public  void  deleteCityInfo( int  cityId)
{
     QueryBuilder qb = cityInfoDao.queryBuilder();
     DeleteQuery bd = qb.where(Properties.CityId.eq(cityId)).buildDelete();
     bd.executeDeleteWithoutDetachingEntities();
}


参考:https://github.com/greenrobot/greenDAO/issues/34


由上可见,使用greenDAO进行数据库的增删改查时及其方便,而且性能极佳。

第二部分 工具库

主要包括那些不错的开发库,包括依赖注入框架、图片缓存、网络相关、数据库ORM建模、Android公共库、Android 高版本向低版本兼容、多媒体相关及其他。

一、依赖注入DI

通过依赖注入减少View、服务、资源简化初始化,事件绑定等重复繁琐工作

  1. AndroidAnnotations(Code Diet)android快速开发框架
    项目地址:https://github.com/excilys/androidannotations
    文档介绍:https://github.com/excilys/androidannotations/wiki
    官方网站:http://androidannotations.org/
    特点:(1) 依赖注入:包括view,extras,系统服务,资源等等
    (2) 简单的线程模型,通过annotation表示方法运行在ui线程还是后台线程
    (3) 事件绑定:通过annotation表示view的响应事件,不用在写内部类
    (4) REST客户端:定义客户端接口,自动生成REST请求的实现
    (5) 没有你想象的复杂:AndroidAnnotations只是在在编译时生成相应子类
    (6) 不影响应用性能:仅50kb,在编译时完成,不会对运行时有性能影响。
    PS:与roboguice的比较:roboguice通过运行时读取annotations进行反射,所以可能影响应用性能,而AndroidAnnotations在编译时生成子类,所以对性能没有影响

  2. roboguice 帮你处理了很多代码异常,利用annotation使得更少的代码完成项目
    项目地址:https://github.com/roboguice/roboguice
